repeater中嵌套绑定RedioButtonList问题？请求完整的代码块。谢谢

Question

html中：
<asp:Repeater ID="Repeater1" runat="server" OnItemCommand="Repeater1_ItemCommand">
<ItemTemplate>
<tr>
<td>
<%#Eval("M_Addate", "{0:yyyy-MM-dd}")%>
</td>
<td>
<p style="width: 180px;">
<%#Eval("M_Title")%></p>
</td>
<td>
<asp:RadioButtonList ID="RadioButtonList1" runat="server" OnSelectedIndexChanged="RadioButtonList1_SelectedIndexChanged"
AutoPostBack="true">
</asp:RadioButtonList>
</td>
</tr>
</ItemTemplate>
</asp:Repeater>
CS中：
protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e)
{

//RadioButtonList zj1 = (RadioButtonList)e.Item.FindControl("RadioButtonList1 ");
//HiddenField Mbit = (HiddenField)e.Item.FindControl("M_Bit");

//if (Mbit.Value.ToString() == "True")
//{
// zj1.Items[0].Selected = true;
//}

if (e.Item.ItemType == ListItemType.Item)
{
RadioButtonList rbl1 = (RadioButtonList)e.Item.FindControl("RadioButtonList1 ");
rbl1.DataSource = this.Repeater1.DataSource;
rbl1.DataTextField = "M_Bit";
rbl1.DataValueField = "M_ID";
rbl1.DataBind();
//if (Repeater1.Items[e.Item.ItemIndex].DataItem == "True ")
// rbl1.Items[0].Selected = true;

}
问题是在html中根本没有绑定出来。

Answer 1

事件错误，应该在ItemDataBound事件中处理，并且多加一个判断

protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
//...
}
}

用的着这么麻烦么 简单的问题 在绑定Repeater数据源的时候一起吧数据源给RadioButtonList绑定了不就好了么 在说了你的那种逻辑对么，也就是每次创建项的时候都去绑定RadioButtonList数据源？这个应该是不正确的，就直接一起绑定应该就可以的
